CARD FEEDING AND WEIGHING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 686,072, dated November 5,1901.

Application filed February 18, 1901. Serial No. 47,756. (No model.)

To all whom it may con/06.

Be it known thatI, JAMES HOGG, of Amsterdam, in the county of Montgomery, in the State of New York, have invented new and 5 useful Improvements in Card Feeding and Weighing Mechanism, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

Myinvention relates to the feed mechanism for carding-machines; anditconsists ofaplatform-scale of new construction and a removing mechanism operated in cooperation therewith and with the feed mechanism, whereby the separated fiber is automatically weighed and periodically delivered to the card, with the result that the fiber is delivered continuously and uniformly as to time, speed, and space and in the best condition.

The essential features of myinvention are the feed, of any suitable construction, a platform-scale, with all its levers, bearings, and graduated bar arranged beneath the platform, an inclosing case for the scale parts, a pusher operating at fixed intervals to sweep or de liver the stock from the platform to the feedapron or other carrier, means operated by the platform-scale temporarily to stop the operation of the feed mechanism until the pusher has delivered the stock and returned to its first position, a presser arranged to press and condense the stock to render it more uniform and in better condition for the feed-rolls on the card, and operating-shafts, gears, and

5 connections. The pusher and presser are preferably combined in one part, as hereinafter shown.

My invention will be understood by reference to the accompanying drawings, in which 40 the same reference characters indicate the same parts in all of the figures.

Figure I is an end elevation showing the connections by which the clutch, pusher, and presser are directly operated. Fig. II is a 5 vertical cross-section thereof. Fig. III is a top plan View of the preceding,with portions broken away and portions shown in section. Figs. 1V and V are enlarged detail views in section of the tripper mechanism by which the movement of the vertical or clutch rockshaft and the relation of the clutch members is controlled. In Fig. IV the platform is elevated, in Fig.V depressed by the load. Fig. VI is a top plan View of a portion of the preceding, the position of the parts when the clutch members are separated beingindicated in dotted lines. Fig. VII is a top plan of the clutch and adjacent parts. Fig. VIIIisa detail top plan of the mechanism by which the clutch is returned to engagement. Figs IX, X, and XI'are respectivelyside elevation, top plan, and cross-section of the platform-scale. Fig. XII is a detail thereof enlarged, showing the connection between two scale-levers. Fig. XIII is a side elevation, with portions broken away, of a preferred form of pusher and presser combined in one part. Fig. XIVis a front elevation of the preceding enlarged, portions being shown in section. Fig. XV is an elevation corresponding to Fig. XIV and showing a simple and better form Fig. XVI, another adjusted position of presser.

In the figures, 1 indicates the feed-chute, preferably widening at the bottom, of which 2 2 are the end plates or side frames, 3 the main pulley, at the pulley-shaft carrying pinion A and on its inner end gear B, meshing with intermediate pinion G on suitable stud, which engages with gear D on main shaft E, carrying bevel-gear F on its opposite end, meshing with bevel-gear G on main vertical shaft 6.

Pinion A meshes with large pinion II-on stud J, carrying also small pinion K, meshing withgear L on mutilated-gear shaftM,thr0ugh which the pusher is operated. on shaft M is also keyed pinion N, meshing with gear P on one of the apron-shafts Q. I

On the upper end of vertical shaft 6 is keyed upper bevel-gear S,meshing with bevel- 9o gearTon stud U. From this, through clutch mechanism to be described, gear V and intermediate gear WV, gears X X, pitmen Y Y, and cranks Z Z, are rocked the rock-shafts 7 7, carrying combs 8 8 to comb down fiber through slots 9 9 in the chute-bottom 1O 10, whence it falls in light open condition onto the scale-platform. This platform-scale is inclosed and protected from dirt, dust, and interference in a suitable inclosing box 15, hav- I00 ingdoor16,andis supported onabase-plate 17, carried between the end plates, on which are fulcrum-arms 1919 of different heights for the hearings or fulcrums 2O 20 of the inner forked ends 21 21 of scale-levers 22 22, having at their adjacent inner ends bearings 23 23 and there connected by a link 24 and havingouter forked ends 26 26, with bearings 27 27 for the angle-irons 28 28 or other suitable supports of the platform 29, of any suitable construction. The bearings are all preferably knife-edged and the scale-levers made substantially as here shown, with the double forked ends for the respective bearings 20 and 27. To the inner end of one scale-lever is secured the graduated scale-arm 31, to which is fitted the sliding weight or counter oise 32, which may be fixed at any point, determining the amount of stock which will be weighed automatically and depress the platform.

In Fig. IX are shown nuts and bolts, unlettered, by which the platform 29 is secured in position on a base, unlettered, supported on angle-irons 28.

To one scale-arm (or to the platform, if desired) is attached the tripper 35, extending outwardly through the opening 36 and carrying on its outer end the adjustable tripperpin 37, extending upwardly through a hole 38 in the inclosing shell 39, carrying on its upper surface the stud 40, on which is journaled the swinging dog-arm 42, provided with a stop 43 at its inner end and at its outer end a hinged latch-piece 44, carrying thereon the dog 45, adjustable by means of slot 46 and set-screw 47. The (ripper-pin 37 engages with the dog-latch to elevate or depress it with the platform and tripper. WVhen the tripper 35 is depressed, the dog and latch drop with it and the dog engaging with the teeth of rotating rack 50 on shaft 6 the dog-arm and stop 43 are swung clear of an upper rock-arm 51 on the vertical or clutch rock-shaft 52, journaled in suitable bearings 53 53 on the end plate, and said shaft is turned or rocked by spring 54, whose ends are secured, respectively, to the lower bearing and to a collar 55, adjustable on the rock-shaft by a setscreW, whereby the forked arm 57, secured to the upper end of the rock-shaft, is swung in, carrying with it the gear V and clutch member 61, integral with grooved pulley 62, out of engagement with the outer clutch member 63, and the feed is temporarily stopped until the pusher has removed the fixed amount of fiber from the platform and is returned to normal position. hen this has been effected, the clutch members are returned to engagement by engagement of antifriction-roller 63 on a lower rocker-arm 67, also adjustably keyed on rock-shaft 52, with stud 65 on inner face of mutilated gear 70, constantly rotating on its shaft M, by which also the push-board is operated through the following mechanism: 69 is spring to return dogarm 42 to first position. 70 is a mutilated gear having a limited number of teeth and rotating in the direction indicated by the arrow to engage at each rotation with a corresponding rock-arm or toothed crank 71, keyed on rock-shaft 73, on which is also keyed the pusher-arm 74, having slot 77 at its upper end for attachment of connecting-rod 76, adjust ably connected to the pusher or pusher-board 78 by any suitable means, such as nut 79 79 and ear SO, outwardly extending through slot 66. Pusher is returned to first position by spring 86, connected to crank-arm S7, keyed on rock-shaft 73. On the end plates are secured the end-plate extensions 81 S1, in which is journaled presser rock-shaft 82, carrying the presser 83. On said shaft is also keyed crank 84, by engagement with which of antifriction-roller on presser-arm 74 the presser is rocked down onto the fiber when it has been pushed onto the apron to compress and compact it slightly, rendering it more uniform in thickness. The presser or presser-board 83 is comparatively light, while 84 is a heavy metallic crank which by its weight returns to the position indicated in Fig. I and elevates the presser from the stock into the position shown in Fig. II when the arm 74, carrying the antifriction-roller 85, has returned to its normal position. (Shown in Fig. I.)

The slat-apron or other suitable carrier is arranged on sprockets 91 91 on shafts Q, suitably journaled, the outer longitudinally adjustable in slots 93 93 to adjust the tension of the apron by blocks 94 94 and set-screws 95 95, the apron being driven by pinion N, meshing with pinion P on one of the shaft-s Q.

96 is a roller for holding and pressing the stock lightly, allowing it to pass in good condition to the card-rollers and card. (Here indicated in dotted lines.)

"While the described construction of pusher and presser are successful, I prefer the construction shown in Figs. XIII, XIV, or XV, in which they are combined in the pusherpresser. Here the lower portion a or pusherboard of the pusher-presser is maintained constantly in a vertical position by arms I) b, keyed on studs 0 c, pinned in blocks 14, flattened to [it slots 66, so that they cannot turn therein, but maintain the pusher-board constantly upright. Between block to and collar 0 of arm I) is the arm 6, connected to presserboard (I by linkfand provided with teeth 9 to engage with fixed rack 7L, whereby arm e is rocked when pusher-presser is in forward position and presser-board is swung down onto stock, as indicated by dotted lines in Fig. XIII.

Fig. XV shows a simple and preferred form of the combined pusher-presser. Here sleeves j, flattened to fit the slots, correspond to studs 0 and carry the arms I) and pusher-board a. Shaft 70 is journaled in these sleeves and extends outwardly, carrying toothed arm 6 on its outer end to engage with fixed rack hand arm on within, connected to the presser-board to swing it down when .the shaft is rocked. It is evident that the presser-boardmay be arranged to come down parallel to the apron or at an angle thereto (indicated in Fig. XVI) to compress the stock nearest the card-rolls more than that at a distance therefrom, tending to make it more uniform with the preceding stock.

The operation of my mechanism will be clear from this description. The scale being set to Weigh a predetermined amount at each operation, the feed mechanism must be operated at a sufficient rate of speed to bring down that amount to depress the platform and stop the feeding mechanism through the tripper mechanism before the pusher-presser comes into operation, which is effected at fixed intervals. The feed after each quantity of stock has been weighed must be stopped a sufficient length of time for the pusher-presser to remove the stock to the carrierand return to its original position. The pusher-board then removes the stock from the platform to the apron, the presser-board condenses it, and the parts return to their original position.

Heretofore scales have been used with cardfeeders, but exposed, subject to wear, and not positively fixing the amount of stock nor deliveringit in uniform condition nor uniformly andcontinnously. Thepartsandconnections have been complicated and liable to wear.

1 In my invention I haveintroduced new features, a new mode of operation, and a simple tripper and connecting mechanism by which all the parts cooperate to the result. The scale is well adapted to its work. The pusher and presser are positive and yet delicate in operation, delivering the stock as it comes from the feed with certainty, uniformity, and in practically thebestcondition. Alltheparts are strong, simple, durable, and combined to cooperate in a single compact machine.
